Figure 3.

Cell viability is affected by H₂O₂ via activation of the Fas/FasL pathway. Viability of cells pretreated with Kp7–6, a Fas/FasL antagonist, or vehicle and treated for 2 h with or without H₂O₂. Results shown as mean ± standard error of the mean (SEM; n=5). Asterisk indicates significant effect of Kp7–6 preventing cell death caused by H₂O₂ (one-way ANOVA and the Student–Newman–Keuls (SNK) test; p<0.001).
